Chicago Nightlife



I.O. Review

Formerly called ImprovOlympic, I.O. is the city's home to long-form improvisation. The signature piece is "The Harold," in which a team of improvisers explores a single audience suggestion throughout a series of stories and characters until they all eventually weave back together to fit with the original audience idea. No drink or age minimum.
